Ahh. There are plenty of threads on here covering that already. Never heard of powertrax, personally. Are they compatible with the 4x4 ecu? Are they an airlocker? It depends if you want a rear locker. My view - get a replacement, either new or off a scrapper. The one you have will be duff. There's no tapping it with a hammer. Inside will most likely look like a beach. As long as you have gone back and forth, turned the wheel etc and it still hasn't engaged, it's stuffed.

IIRC the powertrax is a "lunch box locker" like the Ozzy Locker etc.  In other words it is an automatic locker, very easy to fit - I think with many of them you don't even have to strip the diff fully.  I had a detroit auto locker in a heavy LWB Defender and it worked great (they are a bit more than the powertrax though), but I have heard of reports that they can be a pain in shorter/and or lighter vehicles. Some folk love them, some folk hate them. Some clank and bang when they unlock, and some people report "interesting" handling characteristics with them.  I never had a problem with that though.

Hey Gil. Not sure that we all understood that. You may have been using words that have little meaning here in the UK. Can you explain a little.

Lunch box?
Ozzy?
Auto locker?
Powertrax?

Honestly not being funny, it's just I'm not sure that we have this stuff here. We could go with an ARB Air locker on a 90, but this doesn't help with the 4x4 ecu and the ABS - but it is possible. That's about it.

Hi LC -
an auto locker/lunch box locker/Ozzy or whatever are all fairly similar in that they are permanently locked, unlocking automatically when the car turns a corner.  They are fairly popular (esp the slightly more expensive and very strong Detroit 'No-spin') with the Landrover crowd - often combined with a Truetrac helical geared torque biasing diff in the front.  On part time 4bys like my troopy it is not unknown for people to fit autos front and rear.  

One advantage is that in some cases they can be fitted by only removing the side gears in the diff, but as I say some people report strange handling characteristics and they are maybe not for those that don't realise they are there!  For others the fact that there is no air/electrics and nothing to think about are major plus points.  

Interestingly they are also used in some wheeled CAT equipment (i.e. big Detroit No-Spins), so they are strong!  It might not be related (could be rubbish pattern parts) but in my old Defender I did notice a fairly fast rate of wear of driving members/half shafts and tyres).  For occasional use the Toyo e-locker or TJM/ARB pneumatic selectable locker is perhaps a better if more expensive route.

Cheers buddy. That's interesting. Not heard of that. Don't think that we can get those easily (cheaply) here for the 90. No need really. The RDL when working is spot on.
